I like these questions....I am a "show me the real data" kinda guy.
This debate reminds me of the story from Medieval times when a group of
Monks debated for a couple of years how many teeth a young horse had. Some
argued the number was 40, other 42. A young Monk who had only been in the
Monastery for a few years had a epiphany when he asked the question, "Since
we do not really know how many teeth a young horse has, let us go forth,
find a young horse and count his teeth."
The young Monk was defrocked for being too worldly.
My point: why not put a 10m antenna at 200ft in a area where the HAAT is
reasonable, the ground has good reflectivity and take the measurements?
Or why don't we go and make some measurements at the stations of some of
the excellent stations mentioned here previously. In other words, answer
these well versed question of RLVZ? This would surely make a ground
breaking article from which all could read, study, and benefit.
